The modification of the samples is a result of a steaming process at different temperatures in dependence of time. It was found that dealumination controls the hydrophilic behavior of NaY and contributes to defined low desorption temperatures. Similar to microporous SAPO's steamed Y-zeolites can be used for low temperature applications of heat transformation and thermal adsorption storage.}, language = {en} } @article{HerzogJaenchen2016, author = {Herzog, Thomas H. and J{\"a}nchen, Jochen}, title = {Adsorption Properties of Modified Zeolites for Operating Range Enhancement of Adsorption Heat Pumps through the Use of Organic Adsorptive Agents}, series = {Energy Procedia}, volume = {91}, journal = {Energy Procedia}, issn = {1876-6102}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:526-opus4-6614}, pages = {155 -- 160}, year = {2016}, abstract = {Faujasite zeolites with the highest possible Al-content and different cations as well as a dealuminated zeolite Y have been chosen to study the impact on the adsorption behavior in view of differed adsorptive agents for heat pumps or thermochemical storages.
